How to Play WebM Video on YouTube

If you want to try WebM, the open video format released by Google, you first need a browser that supports it. For now, WebM is not supported in a stable version of a browser, but you can install a Firefox nightly build or an Opera build. I download Opera 10.54, which is more stable than the nightly builds of Firefox.

After installing the browser, go to YouTube's HTML5 experiment and click on "join HTML5 beta". To find videos that are available in the WebM format, use YouTube's search feature and append &webm=1 to the URL, like this: http://www.youtube.com/results?search_query=web&webm=1.

Click on a video and you'll notice that YouTube no longer uses Flash or H.264. There's even a messages that makes the video player more cluttered: "HTML5 * WEBM".


YouTube converted a small percentage of videos to WebM. A search for [web] returns 4,610 WebM videos, while millions of other videos aren't available yet in this format. Check Opera's blog post for more information about the WebM format, embedding WebM videos and more examples of WebM videos.

  1. It doesn't work for me. I just get a spinning logo instead of the video (I'm using the Labs build of Opera that has WebM support added).

  5. I don't get what the point of the exercise is if we have to get proprietary flash in order to play WebM content within a HTML5 (draft) and WebM enabled browser. Sure Google gets to give Apple the finger via MPEG-LA. But the internet isn't any freer or accessible as long as we still have to run these videos via flash and Adobe remains the guardian of all media on the net.

  6. @Anonymous:

    Of course you don't need Flash to play WebM videos. That's the whole point of adding native video support in web browsers: playing videos without installing plug-ins.

  9. Full screen DOES work, but you need to click on the "clip" icon next to the full window icon, then expand THAT window.
